Overview. The differences between vascular and non-vascular plants are clear: vascular plants have a vascular system that transports water and minerals, and non-vascular plants don't. However, there are many important similarities between the two groups.
Circulatory Systems. Another difference between annelids and arthropods is their circulatory system. Annelids and humans have closed circulatory systems in which the heart pumps blood into vessels. The blood is always contained in the vessels -- it does not enter the rest of the body.
